CESSPOOL-WELL.

SPEGIF1CATION'forming part of Letters IPatent No. 292,953, datedfebruary 5, 1884. Application filed June 22, 1883. (No model.)

provement in Cesspool-Vells; and we do hereby declare the following tobe a full, clear, and

. exact description thereof. i

yIO

As heretofore usually constructed, cesspoolwells have been madewith thepipe which connects with the sewer running directly into the well. Thisconstruction has been found very obj ectionable, because the coarsermatters in the well have-clogged the mouth of the pipe and stopped thedischarge from the well, causing it to iill up rapidly and requirefrequent cleaning. It has been suggested to cover the mouth of the pipewith a grating or screen, also placed in the well. The purpose of ourinvention is to obviate this objection and construct the well with anexternal chamber extending up the side, and provided with a gratingbetween the Well and chamber, and having the dischargepipe opening intothe chamber, so that the coarser matters will be prevented fromobtaining access to the mouth of the discharge-pipe.

To enable others skilled in the art to make and use our invention, wewill noW describeit by reference to the accompanying drawings, in Which-Figure l is a vertical section, and Fig. 2 a cross-section on the line ma: of Fig. 1.

The well a is constructed in the usual way. Connected to it is achamber, b, of any desired size, and communicating with the well a bymeans of an opening, c, in which there is a grating, d, of any desiredconstruction, having the interstices between the bars ofthe requiredsize to prevent the passage of the larger Inatters in the well to thechamber. The inner end of the discharge-pipe e terminates in the chamberb, and its outer end runs down to a sewer, j', in the usual way. By thisarrangement the larger matters, such as are liable to clog thedischarge-pipe, are prevented from obtaining access to it, so that thewell is at all times properly drained, and there is no danger of thepipe becoming clogged.

lt is admitted that prior t0 our invention sinks and similar structureshaving gratings and perforated division-walls for preventing theclogging of the end of the soil-pipe had been devised. It is alsoadmitted that privywells having a screen or grating over the end ofthesoil-pipe'are old, and we disclaim such constructions.

We ydo not limit ourselves to any'particular form or construction of thechamber b and grating d, but claim them, broadly, in connection with acesspool-well.

lVhatwe claim as our invention, and desire to secure by Letters Patent,is-

The combination of the well a with the auX- iliary chamber b, grating d,dischargepipe'e, and sewer f, substantially as and for the purposesdescribed.

In testimony whereof we have hereunto set our hands this 20th day ofJune, A. D. 1883.
